Tiling multiple monitors to increase the amount of screen space has become an area of great interest to researchers. While previous research has shown user performance benefits when tiling multiple monitors, little research has analyzed whether much larger high-resolution displays result in better user performance. We compared user performance time, accuracy, and mental workload on multi-scale geospatial search, route tracing, and comparison tasks across one, twelve (4×3), and twenty-four (8×3) tiled monitor configurations. We also compare user performance time in conditions that uniformly curve the twelve and twenty-four monitor displays. Results show that curving displays decreases user performance time, and we observed less strenuous physical navigation on the curved conditions. Depending on the task, the larger viewport sizes also improve performance time, and user frustration is significantly less with the larger displays than with one monitor.

Maps are used by almost everyone in society during the course of their lives. However, when maps are used with computers they are almost always used with small, low pixel count displays, such as desktop monitors. We performed two experiments involving map usage with various tiled display configurations (one monitor, four monitors, and nine monitors). The first experiment focused on basic map navigation tasks and the second experiment focused on how to maximize the effectiveness of the details-ondemand interactive technique with large, high pixel count displays. We conclusively found from the experiments that finding objects and route tracing in maps was performed on average twice as fast on the nine monitors as the one monitor. We also found that participants on the nine monitor configuration had 70 % less mouse clicks, 90 % less window management, and a general accuracy and performance improvement over the one monitor. This indicates improved insight for large, high pixel count displays.

We describe an implementation that has users `ick &apos; notes, images, audio, and video les into piles beyond the screen of the PDA. This scheme allows the PDA user to keep in-formation close at hand without sacricing valuable screen real estate. It also obviates the need to browse complex le trees during a working session. Multiple workspaces can be maintained in persistent store. Each workspace preserves one conguration of off-screen piles. The system allows multiple PDA owners within ad hoc radio range to share off-screen piles. They point out to each other where a shared pile is to reside in space. Once established, all sharing partners may add to the pile and see its contents. One application is to support biodiversity researchers in the eld, where they gen-erate data on their PDA and need to keep it organized until they return to their eld station. We conducted an experiment where participants used our system with up to ten simultane-ous piles. Not only were they able to operate the application, but they remembered the location of piles when placed in different physical environments and when asked to recall the locations several days after the experiment. We describe gen-der differences that suggest particular design choices for the system. ACM Classication H5.2 [Information interfaces and pre-

For over hundreds of years people have been gathering around tables for the purposes of eating, conversing, working, and entertaining. Co-located collaboration researchers exploring alternatives to traditional &quot; desktop&quot; computers are beginning to exploit the benefits that this familiar environment appears to have for facilitating social interactions. Studies of tabletop collaboration involving traditional media (e.g., paper and pens) show collaborators often partition the tabletop workspace into various areas (e.g., personal and group). Just as partitioning of our physical spaces helps to maintain social order, such territorial behaviour on a tabletop workspace appears to be an important mechanism for organizing collaborative activities. This research further investigates tabletop territoriality, through new observational studies, as well as development of territory-based interaction techniques for tabletop collaboration. Initial results from these observational studies are presented, along with a proposed test-bed environment for exploring territory-based interaction techniques.

Abstract. Rear projection of large-scale upright displays is often preferred over front projection because of the elimination of shadows that occlude the projected image. However, rear projection is not always a feasible option for space and cost reasons. Recent research suggests that many of the desirable features of rear projection, in particular shadow elimination, can be reproduced using new front projection techniques. We report on an empirical study to determine how two of these new projection techniques compare with traditional rear projection and front projection, with the hope of motivating the continued advance of improved virtual rear projection techniques. 1

The use of multiple monitors on a single computer is increasing as the cost of monitors goes down. Unfortunately, little is known how performance and navigation are affected as people increase the number of monitors they use. This paper discusses the outcome of an experiment that tracked the navigation and performance of participants as they played a popular strategy game on one, four, and nine monitors. The results show that having only one monitor was a clear disadvantage in both performance and the percent of time participants navigated. Participants performed significantly better on the four and nine screens than the one screen. Also, the larger the screen, the less participants navigated. On the one screen, participants navigated 27 % of the game, while only 12 % on the four screens, and 6 % on the nine screens. There was also found to be a positive transfer from the smaller to larger screens, but no transfer (positive or negative) from the larger to smaller screens. How results can be generalized to geospatial visualizations, military applications, and surveillance systems are discussed.
